that may not be the best way to pick out a camera. go to a store and handle a few cameras. see if you can comfortably hit all of the buttons without taking the camera away from your eye. what feels good in my hands may not feel good in yours (aka ergonomics). that'll narrow your choices down considerably and then you can research a few models. personally i like the retro style controls of the fuji x (very small) and g series (very expensive). canon is nice too, but bigger and heavier. never used nikon or sony. a lot of people love sony but i never really liked their ergonomics or controls.Thanks for the replies, my budget is up to £500.
I'm trying to adopt the advice principle of:
If you're looking for a camera, choose one that others use.
That way if I have any questions there will be someone to answer them.
